From 0706c67711839c88accaf577ac27f7473137febe Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Thu, 13 Jun 2024 03:21:46 +0300 Subject: ipa: libipa: pwl: Add a size() function Add a size() function to the Pwl class to return the number of points in the piecewise linear function. This is useful, for instance, to validate that all points added with append() or prepend() have been taken into account.
